I already discussed this over the XMOS site, but I was wondering about a simple XMOS Chip breakboard or even XMOS to Arduino shield. With this, we could use the XMOS chip to do heavy DSP processing while keeping the Arduino design.

The Arduino would either send the program to the XMOS chip, or just flash an external flash chip connected to the XMOS chip, or even have the XMOS chip boot from a SD-Card. (possible?)

The idea is that the developer would have the actual XMOS Dev. Kit, once the firmware is good, he/she would just supply users with this. Then they plug the shield to an arduino and have the Arduino code send the firmware to the XMOS chip. Making it much cheaper for users to run those things with an Arduino.
